Migrating a backup set
Migration allows you to continue using a backup set and its accumulated backup data if the physical location of the backup source files or the source computer’s name, IP address, or operating system is changed.
When migrating a backup set, consider the following:
• You cannot migrate a backup set containing special backup items like Windows System State and Services Database to a different operating system. To migrate a backup set containing these items, you must delete all generations of the special backup items and remove them from the backup set's Backup Items Selected list.
• When migrating items from one file system to another, verify the backup set item options (such as permissions and streams) are compatible on the new file system.
• If you perform a bare metal restore from a migrated backup set, ensure you only restore operating system files from the same backup session (if applicable). Otherwise, you might restore a combination of incompatible files from different versions of the operating system.
• If you move data to another server and keep the same path format for the data, the DS-Client continues to backup data incrementally for a migrated backup set. For example, if you move data from e$\data to e$\data or c$\data on the new server, the DS-Client processes incremental backups for those files.
• If you move data to another server but do not keep the same path format for the data, the DS-Client performs an initial backup. For example, if you move data from e$\data to e$\newlocation\data or c$\newlocation\data on the new server, the DS-Client sends new masters of files after migration.
To migrate a backup set:
1. Browse the Backup Sets tree and select the backup set.
2. On the Sets menu, point to Backup Sets, and then click Migrate.
3. On the Select the computer page, browse and select the new network or node path to which you want to migrate the backup set, and then click Next.
NOTE: The selected path is the new backup source location.
4. If the option Ask for network credentials is selected, in the Enter Network Credentials dialog box, specify the user name, password, and (if applicable) the source server from which to connect to the selected network or node, and then click OK.
5. On the Match the source/destination shares page, for each existing location in the Source column, specify the share from which data should be backed up in the Destination column, and then click Next.
NOTE: If the physical location of the source data has changed, the share that you select in the Destination column is the new location of the source item.
• For each share selected for backup (or backed up), you should select the destination share on the computer to which you are migrating. The DS‑Client service restricts the migration to a one‑to‑one match (i.e. you cannot select the same destination share for two different source shares).
6. In the Select directories/files for backup page, ensure that the new path that has been assigned to each backup item is correct, add more items if required, and then click Next. To correct the path, click Back to return to the previous page.
7. In the Specify backup item options page, select the required options.
NOTE: The backup item options that are available depend on the network to which you are migrating the backup set and can differ from the options that were previously available for the backup set.
8. Click Finish.
